Faz's engineering quizz

Valves allow the fuel/air mixture to enter into the combustion chamber. what else do they allow?

• allow the burnt gasses to leave combustion chamber

• allow carbon dioxide into the chamber

• allow the car to be able to reverse

• allow h2o into the camshaft sensor

What is the primary function of the intake valve in an internal combustion engine?

• To regulate the engine temperature

• To lubricate the engine components

• To expel exhaust gases from the combustion chamber

• To allow the air/fuel mixture to enter the combustion chamber

Which component is responsible for opening and closing the valves in an engine?

• The spark plug

• The crankshaft

• The camshaft

• The piston

What happens when the exhaust valve opens in a combustion engine?

• Burnt gases are expelled from the combustion chamber

• Oil is circulated through the engine

• Fresh air/fuel mixture enters the combustion chamber

• The engine cools down

what is the name given to the most common type of valve used in the four-stroke engine?

• The Poppet Valve

• The inlet Valve

• The Gas Valve

• The Exhaust Valve

What is the role of the crankshaft in an internal combustion engine?

• To open and close the valves

• To cool the engine

• To convert linear motion to rotational motion

• To ignite the air/fuel mixture

Which part of the engine is directly responsible for igniting the air/fuel mixture?

• The exhaust valve

• The camshaft

• The spark plug

• The piston

During which stroke of a four-stroke engine does the piston move upwards to compress the air/fuel mixture?

• Intake stroke

• Compression stroke

• Exhaust stroke

• Power stroke

Which stroke in a four-stroke engine is responsible for producing power?

• Intake stroke

• Compression stroke

• Power stroke

• Exhaust stroke

What component in an engine is responsible for timing the opening and closing of the valves?

• The crankshaft

• The camshaft

• The piston

• The spark plug
